IMPROVEMENT IN MACHlNES FQR l'ENONlNG SPOKES.

Specification forming part of Letters Patent No. 123,563, dated February 13, 1872.

To all whom it may concern:

Be it known that I, ALBERT F. Gun, of

. Eastmanville, Ottawa county, Michigan, have invented a Tenon-Truer, Spoke-Sizer, and Beveling-Machine; and I do hereby declare that the following is a full, clear, and sufficient description of the same, reference being had to the accompanying drawing and the letters of reference marked thereon, the same beingmade a part of this specification.

Like letters represent like parts in the several figures.

The object of myinventionis a machine that shall produce perfectly true tenons and bevels upon spokes or other work.

Figure 1 is a perspective view of my machine. Fig. 2 is a view of parts on the back side not visible in Fig. 1. Fig. 3 is a view of the knife detached.

A, represents the bed of the machine. are the feet of the machine, on which it stands. 0 (3, Fig. 1, are two slides, the inner edges of which may be made Vshaped, fitting grooves in the plate D, to secure the proper movement of the knife S and spurs W \V, Fig. 3, andfor the tightening of the same. A A, Fig.v 1, are rests for the slides G O, and are part of the bed A, the back end of the rest A bein g raised sufficient to conveniently admit the insertion of a spoke for the purpose of beveling. T V X It Y Z, Fig. 2, is the beveling attachment. T is a standard, against which the shoulder of the spoke rests to avoid an end movement while the knife passes over it in beveling the spoke, the same being a part of the bed A. V is an adjustable plate regulating the space occupied by the spoke while beveling, and is adjustable by means of thumbscrew Z. X is a movable rest for the lower edge of the tenon while beveling, and is ad justable by means of thumbscrew Y. It is a rest for the outer end of the spoke, and, by be-' ing raised orlowered by a thumb-screw secured to the foot B, regulates the angle of the bevel. a b, Fig. 1, are two rests for'the fiat surfaces of the spoketenon, securing its proper position during the process of sizing, and are movable independent of each other by means of thumbscrews 0 d 6 IL, enabling the operator to take an equal portion off each side of the tenon.

By an independent movement of either end of n the rests a b, a tenon of any desired shape may be cut. K K, Fig. 1, are arms attached to the bed A, to the outer end of which is secured the slotted plate F, which is raised or lowered by means of the thumb-screws m 19. J J, Fig. 1, are slotted gauges to regulate the angle of the shoulder, and are adjustable by the thumbscrews n 0. D, Fig. 1, is a plate acting between G O, to which the knife S and the spurs W WV, Fig. 3, are attached under slide 0, and working fair with the front side of bed A and plates a b. C, 1, is a slide secured to crosspieces A A by means of a screw at each end acting in slots, by the movement of which the knives may be tightened. H, Fig. 1, is a handle connected with the plate D by the arm E, for the purpose of giving motion to theknife S. The tenons of all spokes, whether made by hand or machinery, should be trued, sized, and beveled before being driven into the hubsized, that the tenon may exactly fit the mortise; beveled, that the proper. dish may be given to the wheel; for the more perfect and uniform the tenon and bevel, the stronger and more perfect the wheel. The uniform thickness of the tenon saves unnecessary side pressure of the spokes, thus saving the expense of banding light hubs to prevent their splitting. By two movements of the knife the tenon is made and the shoulder cut perfect and to suit the desire of the workman, saving the laying out of the tenon or shoulder, and yet cutting a shoulder of any desired angle. An 'ineX- perienced hand, with this'machine, can do perfect work, without bruising or marrin g the spoke, thus saving the labor of refinishing.

By the use of the beveling arrangement, first, all the time of laying out and marking is saved, since the spokeis only taken into the hand once, and when laid down is fitted and beveled, ready to drive. Second, much time is saved in driving, as a uniform size and bevel will guide the tenon to its proper place. Third, bya slightmovement of the rest R, any desired angle of the bevel can be obtained.

To size and true a tenon on my machine:

First, arrange all the gauges and movable plates to suit the desired size and shape of the tenon by means of the thumb-screws. Second, raise the plate b above plate a sufficiently that, after one side of the tenon has been trued by resting upon a, the other side may be sized while resting on 1). Third, place the shoulder of the tenon to be sized against the outer edge of plate a, the side of it resting against the bed A, the other end of the spoke resting uponthe slotted plate F and against the gauge J; move the knife from the direction of A, Fig. 1, toward A, when the knife S and spur V will pass over the tenon, truing both the upper side and the upper shoulder. Fourth, turn the spoke over, placing the shoulder just trued against the outer edge of the plate Z), with the edge against the bed A, With the outer end of the spoke resting upon the slotted plate F, and against gauge J. Passing the knife S from the direction of A toward A, and the other side of both tenon and shoulder are trued and sized. To bevel a tenon, place the tenon, after being sized. between the standard T and the gauge V, Fig. 2, with the edge of the tenon to remain unbeveled restingupon the plate X, Withthe other end of the spoke resting upon the gauge R. Pass the knife from the direction of A toward'A, and the upper edge of the spoke will be left with a bevelof any angle for which the gauge isset.

Having thus described my invention, and the Working thereof, what I claim as new, and desire to secure by Letters Patent, is

1. The machine-bed A and plate D, provided with knife S, .connecti'on E, and lever H, in eoinbin ation with the adjustable surface-plates a 1), arms K K, plate F, and adjustable slotted gauges J J, substantially as and for the purpose specified.

2. The beveling attachment T, in combination with the knife S, provided With spurs W, all being constructed and operated in the manner shown and described.
